Antibiotic sensitivity pattern among diabetic patients admitted with urinary tract infection.

Objective: To determine the frequency of types of bacterial pathogens involved in urinary tract infections and antibiotic sensitivity patterns among diabetic patients in the medical units of Khyber Teaching Hospital Peshawar. Study Design: Cross-sectional study. Setting: Department of Medicine, Khyber Teaching Hospital, Peshawar. Period: November 9, 2022 until May 8, 2023. Methods: The study was conducted after the approval of the hospital's ethical committee and the written informed consent of patients. Data was entered and analyzed using SPSS. Patients aged 16 to 80 years of both genders admitted to medical units with diabetes and diagnosed with urinary tract infection were enrolled using a non-probability consecutive sampling technique. Results: In our study, a total of 184 patients were enrolled, with a mean age of 52.08±18.4 years. There were 42.4% male and 57.6% female patients. The most common organism isolated was E. coli in 37% of patients, followed by Klebsiella in 23.9% of patients, Pseudomonas in 6.3%, Enterococcus in 12%, and Proteus mirabilis in 10.9% of patients. The most sensitive drug was Fosfomycin in 89.1% of patients, followed by nitrofurantoin in 81.5%, imipenem in 77.1%, amikacin in 73.3%, Piperacillin/tazobactam in 69%, gentamycin in 67.9%, Trimethoprim-sulfamethoxazole in 66.8%, Amoxicillin-clavulanic acid in 59.7%, ciprofloxacin in 54.3%, ceftriaxone in 51%, and cefixime in 46.1% of patients. Conclusion: E. coli is the most common organism isolated in urinary tract infection in diabetics and Fosfomycin is the most sensitive drug for treatment.
